PNELJNIATIC` ELEVATOR AND WEIGHR.

SPECIFICATION forming part of Letters Patent No. 641,045, dated January9, 1900. Application filed October 16, 1899. Serial No. 733,744. (Nomodel.)

To all 'Lc/tom it may 'concer/u Be it known that I, JAMES B. SCHUMAN, acitizen of the United States, residing at Columbia City, in the countyof Whitley and State of Indiana, have invented certain new and usefulImprovements in Pneumatic Elevators and Weighers, of which the followingis a speciiication.

My present invention relates to that class of apparatus which forms thesubject-matter of Patent No. 603,925, issued May l0, 1898, to rlhePneumatic Elevator and Weigher Company upon my application; and itconsists in certain new and improved features incident to a differentform of machine.

Said invention will be rst fully described and the novel featuresthereof then pointed out in the claims.

Referring to the accompanying drawings, which are made a part hereof andon which similar reference characters indicate similar parts, Figure lis an elevation of a machine embodying my present invention as seen fromthe dotted line l l alongside Fig. 2,-the dischargingspout being swungout at right angles with the body of the threshing-machine or separator'to which the elevator is attached; Fig. 2, a side elevation of saidmachine, the delivery-spout being swung around to a position in linewith the body of the threshingmachine or separator; Fig. 3, a verticalsec-` tional view, on an enlarged scale, through the weigher-hopper andadjacent parts as seen from the dotted line 3 3 in Figs. 2 and 4 5 Fig.4, a vertical sectional view as seen from the dotted line 4 4 in Fig. 3;Fig. 5, a horizontal sectional View showing the receiving hopper in planas seen from the dotted line 5 5 in Figs. 2 and 4; Fig. 6, a top or planview,.on a still further enlarged scale, of the hinge and adjacent partsas seen from the dotted line 6 6 from the dotted line l0 10 alongsideFigs. 2 and 8; and Fig. 1l, a detail sectional view on the dotted linel1 ll in Fig. 10. y

The fan casing or housing l (generally and hereinafter called theelevator-boot@ and the elevating or delivery wheel W andblastfanFcontained therein are similar, generally speaking, to thecorresponding parts shown and described in Letters Patent No. 603,925above referred to, although somewhat4 improved in form, and thereforeneed not now be further described herein. This boot is shown in sectionin Fig. 2 to show the form and construction of said wheel and fan. Theelevator-pipe is composed of two sections 2 3 and extends up from theneck of said boot to the height required. In this type of machine theelevation desired is considerable,`and the pipe is consequently quitetall. At about the level of the top ofthe threshing-machine or separatorS said sections are united by a peculiar hinge composed of two parts 4and 5,

by which, as best shown in Fig. 7, the ends of the two pipe-sections 2and 3 are brought closely and neatly together. In order to insure anexact registry, a small lip is `preferably formed on one part of thehinge and a corresponding annular groove in the other, which matchtogether, as shown. Circular ribs r may also be provided to receive andprotect the ends of the pipe. The hinge also forms a portion of a trussby which the pipe is supported. From the lower part 4 four truss-rods 6extend down to the neck of the boot or housing, where their lower endsare secured, and from the upper half 5 four other truss-rods 7 extendupto a ring 8 on theV i pipe 3 near its upper end. As will be readilyseen, this arrangement forms a perfect truss. The two parts 4 and 5 ofthe hinge are connected together on one side by the hingepintle 9 and onthe other side by a suitable lockingbolt l0, the latter of which iseasily lloosened and moved out of engagement with the separator S bystay-bars, as 11,12, 13, 14,'

IOO

and 15, the two latter of which are suitably secured by appropriatebolts to the part 4 of the hinge and to the top of the separator S.These, as will be readily seen, can be attached in any desired numberand at any desired angles and are capable of being adjusted as may bedeemed best. A

At the upper end of the pipe 3 is the curved separating-head 16, theupper or outer surface of which is composed of perforated or reticulatedmaterial. The weighing-hopper 17 is suspended by ears e and bolts b tothe ou ter or discharging end of said head by means of a frame 18, whichis also preferably connected to the pipe 3 below the head 16. Thisconnection is preferably made, as best shown in Fig. 2, through thereceiving-hopper 20, the carrying-arm 21, secured to the upper endthereof, and the semicircular clamp 19,which, with the adjacent andsimilarly-formed end of the arm 21, fits onto said pipe 3, as best shownin Fig. 5.

The receiving mouth or hopper 2O above mentioned is positioned directlybelow the weighing-hopper 17 and is carried from the pipe 3 by suitablebracket-arms 21 and 22, the outer ends of which are semicircular informand fit against the pipe 3 and are secured onto said pipe by clamps 19.It will be seen that by this arrangement the receiving mouth or hopperand the weighing-hopper are both strongly and rigidly supported from thepipe and are held rmly in line with each other. The supports 2l and 22being between the Weighing-hopper and the tu rn-table by which thedischarging-pipe is supported, the latter exerts no strain upon theweighing-hopper, and therefore there is no danger that the moving of thedischarging-pipe on the turn-table will operate to disturb theadjustment of the scale mechanism or cause the weighing-hopper to bindon its bearings or be varied in its relation to adjacent parts, whichwould be liable to occur were the receiving mouth or hopper suspendedaltogether upon the weighing-hopper frame.

As best shown in Figs. 2, 3, and 4, there is a turn-table track t,formed on the lower end of the receiving-hopper 20, and upon thisturn-table track is mounted a turn-table 23, to which in turn is hingedthe upper end of the discharging-pipe 24 by means of a hingepivot 25.This discharging-pipe 24 has a gate G, pivoted at g in a circular frameG at the lower end and is supported at any desired angle by means of abrace 2G, the upper end whereof is forked and bears against a suitabledetent, as a lug 27, on bands on said A pipe, (each of which bands ispreferably composed of the halves 28 and 29,) and the lower end of whichengages with the outer end of an arm 30, carried by the upper hinge-part5. As will be seen, especially by an examination of Fig. 2, the arm 30extends out such a distance that the point of attachment of the brace isperpendicularly below the center of the re` Vceiving mouth or hopper 2Oand the turntable which is carried thereby, so that in whateverdirection the discharging-pipe is.

turned the bracing action is the same.

The machine above described is the result of much study and experiment,and actual use has demonstrated its high practical efficiency. It notonly performs the work of elevating and loading the grain with greatrapidity, but it also cleans and scours it, thus improving itscondition.

Having thus fully described my said invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. The combination, in a pneumatic elevator and weigher, of theelevator-boot, suitable elevating-wheels therein, a pipe leadingupwardly from the neck of said boot, a separating-head on the top ofsaid pipe, a weighinghopper supported from said pipe andseparating-head, a receiving mouth or hopper arranged below saidweighing-hopper and connected to the pipe below the head, adischarging-pipe mounted by means of a turn-table and hin ge connectionto said receiving mouth or hopper, a support perpendicularly below thecenter of said receiving-hopper and the 'turn-table thereon, and abrace-bar extending from said support to said dischargingplpe.

2. The combination, in a pneumatic elevator and weigher, of the boot,suitable elevating-wheels within said boot, a pipe leading from the neckof said boot upwardly and composed of two sections joining at about thelevel of the height of the separator, a hingeand-truss structure at thepoint of union, and truss-rods running from the two halves of saidstructure downwardly and upwardly respectively, whereby the sections ofthe pipe are stronglybraced and supported, substantially as set forth.

3. The combination,- in a pneumatic elevator, of the elevator-boot, thetwo-section pipe leading therefrom, the hinge-and-truss structure at thepoint of union of the two sections of pipe, the same being composed ofthe two parts 4 and 5 united at one side by the hinge or pivot 9 and atthe/other side by the hingebolt 10, and truss-rods running from thelower hinge-half 4 to the neck of the housing, and other truss rodsrunning from the upper hinge-half 5 to a ring near the top of the upperpipe-section, said several parts beingconstructed, arranged andoperating substantially as set forth. c

4. The combination, in a pneumatic elevator, of the boot, the pneumatictube or pipe leading upwardly from said boot, a weigher supported fromthe discharging end of said pipe, a receiving mouth or hopper supportedfrom said pipe below said weighing-hopper, and a discharge-pipe swiveledupon and leading from said receiving-mouth or discharging-hopper,substantially as set forth.

5. The combination, in a pneumatic elevator, with the conveyer-tube, itsseparatinghead and weigher mechanism suspended from Ire izo

7. The combination, in a pneumatic eleva tor, of the elevator-boot, theconveyer-tube, aseparating-head on said tube, a hopper, and connectionsextending upwardly from said hopper to said head and laterally from saidhopper to said tube, whereby said hopper is strongly supported and heldin place.

In witness whereof I have hereunto set my hand and seal at Indianapolis,Indiana, this 6th day of September, A. D. 1899.
